You can see both here http://notes.zahoryzontnik.com/

The other link posted above contains some useful info, but without the detailed description it woukd be difficult to make use of it.

I used another swd probe (jlink) but anyone will do. I’m connecting to the rk3566 chip using swd through the SD card slot so you need emmc chip if you want to use this method. Alternatively you can wire another SD port of your board makes this available.
